UNITED STATES PATENT i cram-E;

Tioallwkom it concern:

, known that I, Manna!) D. PAYNE, a citizen OfflIB United States and aResident of Newark, in theieannty of Essex and State of New Jersey, haveinvented a new and lmpnovedfilo dnbf which the fol lowing is a full,clear, and exact description.

This invention relates to improvements in building blocks and hasparticular reference to a reinforced concrete block.

An object of the invention is to provide an improved block of simple andractical construction in which is embedde a reinforcing element soformed and arranged as to impart maximum strength and durability to theblock.

The above and other objects will appear more clearly from the followingdetailed description, when taken in connection with the accompanyingdrawing, which illustrates a preferred embodiment of the inventive idea.

In the drawing Figure 1 is a perspective view of the block constructedin accordance with the invention and showing the reinforcing elementembedded therein; and

Figure 2 is a section substantially on the line 22 of Figure 1. I

The body 3 of the block which is of substantiall rectangular formationis made of a suitab e mixture of sand and cement and provided in eachend thereof with a groove 4 which combines with the groove of theadjacent blocks to form an air space in a wall constructed of saidblocks. The face 5 of the block is made of a mixture referabl of cementand waterproof material and is ormed with portions 6 and 7 which projectbeyond the top and one end, respectively, of the body of the block. Atthe opposite end and also at the bottom of the block the face 5terminates short of said end and bottom so that when the blocks areassembled to form a wall the portion 6 of one block will overla thebottom edge of a superimposed bloc While the portion 7 will overlap thatend portion of t e next adjacent block in the same horizontal planewhich rojects beyond the end of the face 5 of the atter block. By thisoverlapping arrangement the blocks, when combined to form a wall, are sointer-related that a secure joint will be provided which will haveconsiderable effect in excluding moisture.

A substantially U-shaped reinforcing element 8 inthe form of a rod isembedded in the block. This rod is bentto provide a pnadicallycontinlunls series of angularl=y arranged-portions 9 and-1O whichcombine to increase the effective width of thereinelement Theintermediate portion of said element is embedded-in the block at a pointadjacent the upper surface of the body portion thereof and extendslongitudinally of the front face of the block. The portions 9 and 10combining to form the intermediate'section of the element are arrangedin a plane parallel to the top and bottom of the block and the effectivewidth of said intermediate section is such that parts of the portions 9and 10 will be projected into the rear of the face 5 and beyond the linedefining the front of the body 4 of the block, so that said intermediatesection will not only aid in reinforcing the body but also the frontface 5. The end sections of the reinforcing element are formed bybending the rod so that said sections will extend from the front of thebody to the back thereof and diagonally downward between opposed cornersof the end of the block. In thus bending the end sections the relationof the portions 9 and 10 thereof with respect to each other ismaintained so that the plane of said ends will be coincident orparallelto a plane through an end of the block extending between said opposedcorners, as shown in Figure 2.

What is claimed is:

l. A reinforced building block including a body having a face, and areinforcing element embedded in said block and having a section thereofextending longitudinally of the block adjacent the top thereof and othersections extending diagonally between opposed corners of the ends ofsaid body.

2. A reinforced building block including a body having a face, and areinforcin' element embedded in said block and having a section thereofextending longitudinally of the block adjacent the top thereofand othersections extending diagonally between 0 posed corners of the ends ofsaid body, t e first-named section of thereinforcing element havingportions thereof embedded in the body of the block and other portionsembedded in the face thereof.

3. A reinforced building block including a body having a face. and areinforcing element embedded in said block and formed of a single lengthof rod bent to provide a series of angnlarly arranged portions and alsobent to provide a plurality of sections, one of the sections beingembedded in the block adjacent the upper portion of the face thereof andthe other sections extending from the first-named section diagonallybetween opposed corners of the ends of the block, the plane of thefirst-named section being parallel to the top and bottom of the block,while the planes of the other sections are parallel to a plane throughan end of the block extending between opposed corners thereof.

4. A reinforced building block including a body, a face for said bodyhaving certain edges projecting beyond adjacent edges of said body andother edges terminating short oi. adjacent edges of the body, and areinforcing element embedded in said block and having an intermediatesection arranged longitudinally of the top of the block and providedwith portions parts of which are embedded in the body and other parts insaid face, said reinforcing element also including end sections whichextend diagonally downward from said intermediate section and across theends of said body.
